Question 1

What is Diffwise?

Accepted Answer

Diffwise is an AI code review tool that installs as a GitHub App and reviews every pull request with three specialized agents — security, performance, and conventions — running in parallel. It goes beyond individual PR comments to provide cross-repo anti-pattern tracking, resolution velocity metrics, and a dashboard showing team-wide engineering health.

Question 2

How is Diffwise different from other code review tools?

Accepted Answer

Most code review tools comment on individual PRs and forget. Diffwise adds an intelligence layer: it tracks recurring anti-patterns across all your repos, measures how fast your team resolves findings, identifies hot files that attract the most bugs, and provides a unified dashboard for engineering quality. It's engineering intelligence, not just code review.

Question 3

What programming languages does Diffwise support?

Accepted Answer

Diffwise supports all major programming languages including TypeScript, JavaScript, Python, Go, Rust, Java, C#, Ruby, PHP, Kotlin, Swift, and more. The AI agents analyze code patterns, security vulnerabilities, and performance issues regardless of the language used.

Question 4

Is Diffwise free?

Accepted Answer

Yes, Diffwise is free to install and use. Install the GitHub App in 30 seconds, select your repositories, and start getting AI-powered code reviews on every pull request at no cost.

Question 5

Does Diffwise store my code?

Accepted Answer

No. Diffwise processes your code in real-time during review and stores zero bytes of your source code. Only metadata — findings, patterns, and metrics — is retained to power the analytics dashboard.

Question 6

How fast are Diffwise code reviews?

Accepted Answer

Full reviews complete in under 2 minutes with three agents running in parallel. Incremental reviews — after you push fixes — complete in under 30 seconds and use 60% fewer tokens by only analyzing what changed.

Question 7

How do I install Diffwise?

Accepted Answer

Install Diffwise in three steps: 1) Install the GitHub App from github.com/apps/diffwiseapp, 2) Select which repositories to monitor, 3) Open a pull request. That's it — no config files, no YAML, no CI changes required.

Question 8

What is incremental code review?

Accepted Answer

Incremental code review means that when you push fixes after an initial review, Diffwise compares your changes against the previous review and tells you exactly what's fixed, what's still open, and what's new. Previous review comments collapse automatically, keeping your PR clean.
